To all'whom it may concern: v

Be t known that I, WILLIS M. T HAYER, a

citizen of the United States, residing at i ositive element in' a stationary storager attery ldesigned for heavy work, but it is -Hartford, in the county of Hartford and State of Connecticut, have invented` a new and useful Storage-,Battery Grid, of whichthe following isa specification.

This invention relates to a grid which is more particularly adapted to .be used fora equally applicable for use in a portable A'battery .orin- Aa' battery designed for light '-Wor'k, and itfalso can 4be used fora negative element in a storage battery.

The object of the invention is to produce i" a storage battery element 4which is sim le to make, easy to -put together, and whic has e great mechanical strength for its weight, can

channels.

be readily handled without injury, ,and is durable and very efficient in action.

The illustrated embodiment of the invention has 51a' grid member formed of a plural number of bars with anged edgesA that extend parallel with each other in such relation ,as {to .form longitudinal ockets between them,";i and an active mem er formed of a plural vnumber of rods that extend parallel with each other in such manner .that they :may vbe inserted axially into and be supported by the walls of the pockets between the bars of the grid member. 'I

Figure' 1 of the accompanying drawings shows a-side elevation of a grid member that embodies thisinvention; Fig.- 2 shows an end view ofthe'grid member. Fig. 3 shows a sideelevation of one form of active mem-r ber that may!l be used with this invention. Fig. 4 shows anend view of this active member. Fig'.v 5 show`s a side elevation of the grid vand active members assembled into a comvlete battery felementas in use. Fig. 6

illustrates a different way of assembling the` members. Fig. 7 shows an edge view `of the connecting'post illustrated in Fig. 6. Fig. 8 showsa modified form of the grid.

- The grid member may be formed of any desired number 'of barsl which are recessed upon their upperand lower sides' orA provided with langes `2 on-their edges to forml Thesejjb'ars arearranged -adjacent to and parallel with each othe r so`as'to forinopen pocketslthat. extend longitudinally be-v tweenthem," ,and they maybecast integralA with or other'xvvise suitably'fastened 'toa -post 3 which may; join the ends of the bars,

as shown-in Fig. v1, or may be at the middle burned to, or otherwise joined with a post 5 which preferably connects them at one end. These rods which are represented as circular in cross section, but whichmayhave any other suitable cross-sectional shape, are somewhat shorter `than the length of the pockets to permit growth and are preferably made from soft lead formed into spongy or per-oxid of lead before they are arranged in the grid, but they may be made of other common active material, and the'post joinng the rods may be made of antimonious ead.

In assembling the parts of the element described, the rods of the'active member are thrust into the pockets between the bars of the grid member and the post supporting the rods lead-burned or otherwise fastened to the end s of the bars in such manner that the'rods are supported by the bars. This forms a simple method of assembling the parts and produces a strong grid with the active rods supported by and in contact with the grid bars and having sufficient space about them for the circulation of the electrolyte, which may be ordinary dilutesulfuric acid.

Any desired number of flanged or. recessed bars may be employed in making up the grid memben-and these bars may be of any size l and may have longitudinally extending pockets of any size and cross sectional'shape. The rods of theactive member'would ordinarily be equalin number to the pockets of the grid, and in case that the joining post of the grid bars were at one end, the active rods would be inserted at Ioneend,but if the joining post of the grid were at the center, the

' activeirods would be inserted at bothends of the-grid, asfshown in Fig 8.

V'Ifit is desired, the post for joining the lopen ends of the grid bars can be provided with lugs 6, as shown in Fig-{vand after the active :rods havebeen insertedinto` the pockets this postis connected with the endsof 'the bars in any vsuitable.way. "These lugs are"` preferably I iio ordinary manner.

arranged-so that they extend above and be` low and support the ends of 'the bars when the rods are in the pockets and the post is fastened to the bars. 'These grids can ybe provided with the usual supporting lugs?, as shown in Fig. 8, and any desired number of` elements mounted in a battery cell in the A grid constructed in this manner has great mechanical strength for its weight,4 andthe activematerial issupported and protected in such away that the element can be' readily handled without injury. The amount of vlead burning to properly connect the/parts is very small. Electrically7 the grid member holds the active material in placeallowing for growth, without any tendencyto buckle and the advantages of a for-med and a pasted plateare united, because as the active` material becomes dislodged from its original support it is still held in place in -the pockets so that it can be workedto its full capacity. The active material is always in metallic engagement with the supporting grid, and this active material can be introduced into this form of grid in a number of different forms without departing from the invention.

The invention claimed is -1. A storage battery element comprising a I plural number of bars having anged edges, arranged parallel with each other so as to form open ppckets that extend longitudinally between2 them, a post integral with and j oining said bars at one end, a plural number of active rods located within said pockets, and a post joining said rods at one end, substantially as specified.

` 2. The combination of a plural number of supporting bars arranged parallel with each other so as to form longitudinally extending pockets between` them, a post connecting said supporting bars, a plural number of active rods located Within said pockets `and a post connecting the said rods, substantially as specified. y

3. The combination of a plural number of anged supporting bars arranged longitudinally with `relation 'fo/each other so as to lforni longitudinally extending pockets between them, a plural number of active lrods located within said pockets and supported by said bars, and pos-ts connecting the said Ibars at their ends, substantially as specified.
